COMBINED CANE ANDBURGLAR-ALARIVI.

SPECIFICATION forming part of Letters Patent No. 292,389, dated January 22, `18:54. Application filed November 19, 1883. (No model.)

To @ZZ whom it may concern:

Be it known that I, JOHN B. VAN ZAND'r, of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in a Combined Cane and Burglar-Alarm; and I do hereby declare that the following is a full, clear, and exact description of the invention, which Awill enable others skilled in the art to which it'appertains to make and use the same, reference being had to the accompanying drawings, and to the Y letters of reference marked thereon, which forni a part of this specication.

This 'invention has for itsobject to provide the handle of a cane of such construction asto adapt the cane for use as a det'onating burglar-alarm, whereby the occupant of a room may bearoused from sleep in an attempt being :madeA byunauthorized persons to gain access to his apartment.

To this end the inventionV consists in such details of construction and combination of parts as will be hereinafter distinctly pointed out.

Referring to the drawings hereunto annexed, kFigure l represents the manner in which the cane is suspended over the top of a door, and how, when the door is opened, it is made to descend by gravity and produce an alarm. Fig. 2 is a vertical sectional view of the handle of the cane to show its construction, and Fig. 3 is a view/of devices forming the means of suspension for the cane.

The cane is in all respects similar to an ordinary walking-stick, with the exception of the handle and ferrule. The handle consists of a collar secured to the upper end of the cane, and within which is located a small screw-threaded nut. At the end of the collar is placed a thimble, which is held on by a screw passing down through it and through the nut aforesaid, which'is located within the collar. The upper end of the thimble isvconcave, and the head of the screw isinclined inward from the top thereof, to thus conform to the contour of the said concaved end of the thimble, into which it ts. When the screw is screwed down, the Vinclined face of the head thereof rests against'the corresponding face around the inner edge'of the concavity in the thimble. Between these two faces it is proposed, when desired, to place a 'small percussion-cap, so that* an alarm maybe produced bystriking the head of the cane sufliciently hard to explode the cap. The ferrule is Vprovided on opposite sides with small holes for receiving the ends of a spring-clamp,

:by which the cane is suspended.

Referring to the letters of reference, Arepresents the cane, and B the handle asa whole.

C is the collar, which is suitably secured around the upper end of the cane, said cane being hollowed out for a short distance to admit of the end of the screw.

c'indicates the screw-nut in the collar; d, the screw, whose head is inclined on its Dunder side, and e represents'the thimble having the concaved end, into whichthe screw-head iits.

D represents a devicevby which the cane is suspended. It consists of a piece of wire, f, having linked to one end a spring-clamp, g', whose ends fit into holes on opposite sides of the ferrule ofthe cane. This wire is so bent that when placed in the space or vcrevice between the upper edge of the door and frame the weight of the cane will be sufficient to maintain it (the cane) steady. This spring-clamp could be carried in the pocket onan ordinary key-ring7 and readily detached therefrom when needed.

The operation is as follows: The occupant of the room simplytakes the cane and suspends the same over the top of the door, as

hereinbefore explained.v On the door being slightly opened'the support for the cane is released,whereupon the cane drops and, striking the floor, explodes the cap,` thus frightening away the thief and arousing the occupant of the room.

2. The combination of the cane having collar, as described, and the screw-nut located in said collar, with the thimble e and screw d, said thimble being formed at its upper end for the reception of the screw-head, substantially as set forth.
